Spectncation Aof Letters Patent.

Patented Dec. 1, 1914.

Application tiled April 1, 1914. .Serial No. 823,655.

T o all whom it m ay concern.'

Be it known that I, MINOR E. CHAMBER- Lux, a citizen of the United States, residing in the city of Lebanon and State of Missouri, have invented a new and useful Reinforced Concrete Construction, of which the following is a specification.

This invention Vrelates to reinforced concrete construction, including posts, columns, Walls and various forms of devices and structures composed .of concrete provided with reinforcements.

An object. of the invention is to provide a concrete post having sections of metallic reinforcements embedded therein, and reinforcing elements engaging with and unitinff the different sections of reinforcements and also serving to strengthen the reinforcements and the post structure at the point of union of said sections.

Another object is to provide an improved reinforced concrete post comprising a monolithic body composed of concrete., in combination with a reinforcement embedded in the concrete and composed of sheet metal bentand' folded so as to form two arms or vanes of double thickness and two arms or vanes of single thickness, and one or more sup lemental reinforcements each composed of sieet metal bent and folded to form one arm of double thickness and two arms of single thickness. for engaging and coperating with the first mentioned reinforcement to strengthen the arms of single thickness on said reinforcement.

A further object is to provide a reinforced concrete construction comprising a body of concrete, and a, series of metallic reinforcements embedded in said concrete and'composed ofsheet metal bent and folded to provide laterally extending arms, in combination with metal reinforcing.,r plates engaging with said arms and connecting said reinforcements to strengthen the structure against lateral and longitudinal stresses.

Another object is to provide a reinforced concrete post or column comprising a concrete body. and metal reii1forcements` embedded in said body near the surface thereof, in combination with a metallic reinforcement embedded in said body near the center thereof, and a series of metallic. plates connectingV said reinforcements.

Various other objects and advantages will appear from the following detailed description, reference being made to the accompanying drawings in which- Figure 1 is a longitudinal sectional view of al post embodying my invention. Fin'. '2 isa view enlarged relative to Fig. 1 illustrating the. reinforcing' connecting devices or elements by which the different sections of the reinforcements :i re connected and strengthened. Fig. 3 is a cross sectional view on the'line 3-3 of Fig. Fig. J. is a side elevation of a reinforcing,r device consistin of separate sections of sheet metal one o which is provided with arms of double thickness and arms of single thickness, the arms of single thickness being strengthcned and reinforced by the separate reinforcing element.

Fig. l0 is a view illust-rating thereinforcing devices with the concrete removed. Fig. llnis n perspective view illustrating the yform ot' the connecting plates utilized in the structurr` illustrated in Figs. 1 and 10.

A post utilizing the reinforcements illustrated in Figs. 1 to inclusive. comprises a concrete bodi7 l of the desired dimensions so that the reinforcements ma)- be eiiilieiltled therein. IThe reinforcements consist of a number of sections of sheet nictal bent and folded to form two arms or vanes 2 of double thickness, and two arms 3 of single thickness at right angles to thenrins of double thickness. The arms 2 and 3 extend radially substantially from a common center. and the reinforcing sections employed are intended to 'be arranged end to end. When so arranged the abutting sections are connected and reinforced by suitable reinforcing connections also composed of sheet metal.

Each reinforcing connection is composed lOt) arms 2 of the reinforcing sections when the various elements are assembled, as illustrated in Fig. 3. After the reinforcing connections have been arranged upon the abutting reinforcing sections the arms or vanes are stamped to form openinvs and laterally .extending projections 7. lhe laterally extending projections 7 on the reinforcin connections interlock with the arms 2 and 3 of the reinforcing sections, so that the various parts of the reinforcement are firmly secured together. The openings 6 formed by the projections 7 receive the concrete, so that the reinforcement and the concrete become ver firmly united. The arms or vanes 2 an 3 are also .provided with extensions 4' so that the concrete becomes seated in holes and embeds the lateral projections upon the reinforcing sections throughout their-len h.

The, reinforcement illustrated in' ig. l consists of's single section A of reinforce- "ment, composed of'sheet metal bent to form arms 2 of double thickness andarms 8 o'f single tl1ickness`,"'(Fig.l tif-precisely like the sections of reinforcements-just described. For one or-more-of the `arms 3 of single thickness there is an auxiliary reinforcement extendin substantiallyv from end to end of the rein orcement A.' The auxiliary, reinforcement is formed isely like the reinforcing 'conneetionstween the di'erent sections of reinforcements abovebde'sdribed except that it extends substantially from end to en d of the main reinforcement. l The auxiliary reinforcement consists of an arm 4 of Idouble thickness embracing the'arm 3 of single thickness, and it consists further of two laterally extending arms pressin a inst the arms 2 of double thickness. A

o the arms of the reinforoementfthus assembled are stam d to form holes 6- and to provide laters. extensions 7. The-reinforcement thus formed'i'is embedded in 'the concrete and extends substantially from end to -szend of the post,`constituting a very strong and substantial reinforcement.A

The structure illustrated in Figs. 6, 7 and 8 consists of aconcrete bod and a series of reinforcing members simi ar to the reinforcements above described as em loyed in the concrete posts. The sheet metalforming said reinforcements is bent and folded to form two arms 8 of double thickness and two arms 9 of single thickness. The reinforcemcnts thus formed are spaced at suitable intervals. and the arms 8 and 9 on the different reinforcements are connected by reinforcing plates, the plates arranged in connec'tion with the arms 8 being in di'erent horizontal planes from the plates connected to the arms 9, so that the various connectin pates occupy a staggered relation. Eaci plate consists of two metallic sections 10 stamped to form interlocking lateral extensions 11 whereby the plates are held toether. The plates 10 are provided with aterally extended portions 12, and the arms 8 and 9 are received between the plates 10, the lateral extensions 12 bearing against the arms on the reinforcements as illustrated in Fig. 6. After being assembled the arms on the reinforcements and the extensions 12 on the connecting plates are stamped to form openings 12* and interlocking projections 13, thereby firmly connecting the various pai-ts of the reinforcements to receive all of thek lateral and longitudinal stresses of the structure. This structure is particularly adapted for use in the construction of walls and large columns and pedestals and the like.

The structure illustrated in Fi s. 9, 10 and 11 includes a concrete body o any desired shape embedding in its center one of the reinforcing devices 1l of the typeV previously described. There are also embedded in theconcrete a series of reinforcing devices 15 parallel with the central reinforceme't 14. Each reinforcement 15 is formed pi-cciselv similar to the auxiliary reinforcementillustrated in Fig. 4 and consists of one arm of double thickness and two laterally extending. arms of single thickness. The reinforcements 15 are connected with the central reinforcement 14 by a plurality of connecting devices 16. Each connecting device 16 consists 'of 'a doubled section of sheet metal embraced between the arms of the reinforcement 15 andembracing one of the arms of the reinforcement 14.. The edges of the member 16 are bent to provide lateral extensions 17, and when the reinforcements are assembled the engaging portions -of the several reinforcements are stamped to yform lateral extensions 18 to interlock the parts and openings or holes in which lthe concrete solidiies. The structure illustrated in Figs. 9 and 10 is adapted particularly for use in constructing posts of large' size, columns, pedestals and various other concrete structures.

It will be-understood that there may be various modifications in the construction and arrangement of the different elements of the invention without departure from the spirit of the invention. I do not restrict myself to precise details, but

What I claim and desire to secure by Letters Patent of the United States is:

r1. In a monolithic concrete structure, a concrete body, and a pair of sheet metal reinforcements each comprising a single sheet folded to provide four perpendicularly disposed lateral wings, two of which wings are of a double and the remaining two of a. single thickness of the sheet, the single wings being in alinement with each other, a reinforcing connection clamped closel upon the ed es of single thickness of botii o said rein orcements, and projections on said reinforcements en aging said connection, substantiall as escribed.
